The Lampang cancer registry was established in 1995, with retrospective data collection since 1988. Cancer registration is currently done by passive methods. The registry is contributing data on survival for 40 cancer sites or types registered during 1990-2000. Follow-up has been carried out by passive and active methods with median follow-up ranging from 1-74 months for different cancers. The proportion having a histologically verified diagnosis for various cancers ranged between 30-100%; death certificate only (DCO) cases comprised 0-33%; 67-100% of total registered cases were included for survival analysis. Complete follow-up at five years ranged from 96-100% for different cancers. The 5-year age-standardized relative survival rate was the highest for skin non-melanoma (85%) followed by lip (81%), thyroid (74%), corpus uteri (71%) and penis (71%). The 5-year relative survival by age group showed a fluctuating trend. An overwhelmingly high proportion of cases were diagnosed with a regional spread of disease, ranging from 35-68% for different cancers, and survival was decreasing with increasing extent of disease for most cancers studied.
南邦癌症登记处成立于1995年，自1988年起进行回顾性数据收集。目前通过被动方法进行癌症登记。该登记处正在提供1990 - 2000年期间登记的40种癌症部位或类型的生存数据。采用被动和主动方法进行随访，不同癌症的中位随访时间为1 - 74个月。各种癌症经组织学确诊的比例在30% - 100%之间；仅死亡证明（DCO）病例占0% - 33%；纳入生存分析的登记病例总数的67% - 100%。不同癌症的五年完全随访率在96% - 100%之间。5年年龄标准化相对生存率最高的是皮肤非黑色素瘤（85%），其次是唇癌（81%）、甲状腺癌（74%）、子宫体癌（71%）和阴茎癌（71%）。按年龄组划分的5年相对生存率呈波动趋势。绝大多数病例被诊断为疾病局部扩散，不同癌症的这一比例在35% - 68%之间，并且对于大多数所研究的癌症，生存率随着疾病范围的扩大而降低。
